Alex Google currently doesn't have a customer event pixel for GA4 tracking, once the store is upgraded to Checkout extensibility, they won't be able to track conversions on the checkout page, post-purchase page and the Thank-you page via the Google app only, we need a custom GA4 pixel in all those pages with full data layer.

Joseph Raphael: Hey Joseph, thank you. Our team have just confirmed your message. So the pixel installation becomes very valuable for our merchants. So we are considering to send all customer events from page view to whole checkout process to GA4 via server-side. I will update you once we confirm the solution.🙌

Alex Thank you, it's extremely important as of now, there is no official solution available, even in my PLUS store, I have a workaround implemented but it won't last long.

Joseph Raphael: There is an official demo on how to pass customer events to GTM & GA4 with Shopify Custom Pixel, https://help.shopify.com/en/manual/promoting-marketing/pixels/custom-pixels/gtm-tutorial. Please let me know if you need any support. Meanwhile, we are working on sever-side for checkout process, which you can't just rely on broswer-side pixel.

Alex I already know about it since 3 weeks ago, it's not fully tracking all events and also not working with the new thank you page and order status page.
